Beer glazed lamb fajitas

1# lamb leg steaks
1 lime juiced (reserve half the juice for additional seasoning)
2-3 drops Worcestershire
1 pinch each of sugar, salt and pepper
2 teaspoons vegetable oil
3 ounces Negra Modelo or other dark beer

Season steak with half of the lime juice, Worcestershire, sugar, salt and pepper.
Heat vegetable oil in pan on high heat. Pan sear steak for two minutes on each side.
Deglaze the pan with Negra Modelo, keeping the steak in the pan and maintaining high heat to reduce beer to a sauce. Check for seasoning and add more lime juice, sugar or salt to your taste.  Remove to plate &
let steak rest for 10 minutes, then slice thinly across the grain.
Serve in flour tortillas and top with salsa, fresh chopped ciliantro and your choice of peppers.
